Since the value is a raw u32 from device MMIO, any value is\npossible and if greater than or equal to PCI_STD_NUM_BARS the access goes\nout of bounds.\n\nAdd a bounds check before dereferencing test->bar[bar].\n\nFixes: eefb83790a0d (\"misc: pci_endpoint_test: Add doorbell test case\")\nSigned-off-by: Carlos Bilbao (Lambda) <carlos.bilbao@kernel.org>\n---\n drivers/misc/pci_endpoint_test.c | 5 +++++\n 1 file changed, 5 insertions(+)",
